Colon surgery comprises a high number of patients treated in a gastrointestinal surgery department. Like any major surgery, it may present diverse surgical and medical postoperative complications. In this article we review the most frequent surgical complications of colon surgery: abdominal sepsis, postoperative ileus, bleeding, fistula, evisceration, ureteral lesion, colostomy problems and damage to upper mesenteric vessels. Every colorectal surgeon must know all the possible complications of colon surgery to achieve an early diagnosis and correct management.

we report the case of a recurrent giant pseudopolyp occurring in a patient without a history of inflammatory bowel disease (IBD), with an asymptomatic interval of nine years. Case Presentation: a 51-year-old Caucasian male with no relevant medical history was hospitalized for a subocclusive mass in the right colon, suspected to be neoplastic. He underwent a right hemicolectomy, and the histopathology revealed a giant pseudopolyp without malignancy.

Many advocate adapting surgical technique based on preoperative CT staging as not all patients require complete mesocolic excision (CME) and D3 lymphadenectomy. We aimed to assess the sensitivity and specificity of preoperative CT scans in nodal staging and analyse whether inadequate CT staging could have influenced local recurrences.

Despite the variety of proposed solutions, anastomotic leakage is still a critical complication after colorectal surgery, which causes increased clinical mortality and morbidity. By enhancing microcirculation in the colonic mucosa, the use of Iloprost (Ilo) has shown promising results for the healing of anastomosis. The purpose of this study is to examine the performance of Ilo-impregnated Polycaprolactone:Gelatin electrospun membranes (PCL/Gel/Ilo) on anastomosis repair and intra-abdominal adhesion behavior in the Rat colon.

Objective: Colorectal cancer is severely challenging because of the insufficient understanding of the mechanism underlying its resistance to clinical chemotherapy. The purpose of our study is to investigate the role of the LIM protein Ajuba (JUB) in the chemoresistance of colon cancer and its potential effect on clinical treatment.
Material And Methods: The protein levels of JUB in colon cancer tissues were evaluated using Western blot analysis and immunohistochemistry assays.

Aim: To assess recent colonoscopies and CT scans in conjunction with the feacal immunochemical test (FIT) for possibly downgrading urgent suspected cancer (USC) referrals.
Methods: A retrospective single-centre study was conducted, including all USC referrals for colonoscopy in 2022, excluding anal cancers. The CT and colonoscopy findings for a two-year period prior to the referral, along with the FIT result (if done), were noted.
